SFA Sanipump VX 50.3 T Three-Phase Submersible Pump - Fixed Manual Version

The submersible pump SFA Sanipump VX 50.3 T, reference AP0009, is a professional and robust solution for the evacuation of wastewater and rainwater from pits, sumps, or buried pumping stations. This fixed three-phase version is designed for installations with an external control panel and requires continuous operation, reliability, and durability.

Equipped with a cast iron vortex impeller, this pump allows the evacuation of solids up to 43 mm in diameter, reaching a maximum flow rate of 25.5 m³/h and a head height of up to 14 meters. Thanks to its hydraulic design, it is ideal for applications with loaded water, whether domestic, commercial, or industrial.

The pump body, motor, and impeller are made of EN-GJL-250 cast iron, while the shaft is stainless steel. The sealing system consists of a seal on the motor side and a mechanical seal SIC/Al₂O₃ on the fluid side, ensuring safe and durable operation.

This version does not have a built-in level switch and must be managed through an external control system. It can be submerged up to 10 meters deep and is prepared for intensive use in continuous mode (S1). It comes with a 10-meter power cable (H07 RN8-F, 4x1 mm²).
